title: [Vitamin A, vitamin E and beta-carotene nutritional status and antioxidase level analysis among tuberculosis patients].
abstract: OBJECTIVE
  To investigate vitamin A (VA), vitamin E (VE) and beta-carotene nutritional status and antioxidase level among tuberculosis patients.
  
  
  METHODS
  Totally 70 tuberculosis patients were randomly selected as the experiment group from Tancheng Tuberculosis Control in 2010. And 70 matched normal persons were selected as the control group. Two groups of people were relative nutrition index test which include body mass index (BMI), hemoglobin (Hb), triglyceride (TG), total cholesterol ( TC) , high-density lipoprotein (HDL), superoxide dismutase (SOD), catalase (CAT), VA, VE and beta-carotene.
  
  
  RESULTS
  BMI of the experiment group was 19.13, which was obviously lower than those of the control group which was 21.95 (P<0.05), but Hb of the experiment group was 128.36 g/L which was lower than those of the control group, not with significant statistic differences. For blood lipid level, TG, TC, HDL of the experiment group were 1.54, 4.47 and 1.21 mmol/L respectively, compared with corresponding indexes of the control group which were 1.63, 5.20, 1.30 mmol/L respectively, were all dramatic decline (P<0.05). Antioxidase level contrast between two groups showed that SOD and CAT of the experiment group were 78.20 and 5.24 U/ml respectively, and corresponding indexes of the control group were 83.27 and 9.99 U/ml respectively, so the former was significantly lower than the later (P<0.05); compared with the control group on vitamin level, VA, VE of the experiment group were 0.256 and 1.148 microg/ml respectively which were all lower than the control group which were 0.385 and 1.182 microg/ml (P<0.05), but beta-carotene of the experiment group was 0.048 microg/ml which was slightly lower than 0.051 microg/ml of the control group, not with significant statistic differences.
  
  
  CONCLUSIONS
  Nutritional status among the tuberculosis patients is quite poor, especially antioxidase and VA, VE and beta-carotene level are significantly lower than normal people.
